Optical imaging system for timepiece, portable computer, mobile telephone, spectacles, clothing item, chip card or sticker using array of optical channels with relatively angled optical axes

摘要

The imaging system has a regular array of optical channels provided by a microlens and a detector positioned in its focal plane, for providing an image point from the microimage provided by the microlens, the optical axes of the optical channels angled in dependence on their relative spacing from the centre of the imaging system, to provide a required ratio between the size of the field of view to the size of the image field.
